Title: Improvements in and relating to the manufacture of electrically heated cooking plates
IPC: B28B19/00
Filed: 1933-11-10
Abstract: 413,174. Moulding electric hot-plates. SIEMENS - SCHUCKERTWERKE AKT. - GES., Siemensstadt, Berlin. Nov. 10, 1933, No. 31378. Convention date, March 11. [Class 87 (ii).] In the process of moulding an electric hotplate in which a heating resistance 16 is embedded between upper and lower layers of plastic insulating-material 15 by pressure, the platen of the press is subdivided into a number of yielding plungers 13 which are actuated from the main stamp head 11 through the medium of a rubber cushion 12 or through a cavity filled with steel balls or other pressure-equalizing medium. By this means, the whole surface of the hot-plate is subjected to equal pressure notwithstanding variation in thickness of the layer of material. The work-contacting faces of the plungers may be made concave to facilitate release of the material on the upstroke, and may also be grooved to permit escape of air.

Abstract: 1,270,858. Pressure cooking apparatus. KENTUCKY FRIED CHICKEN CORP. 25 June, 1969, No. 32098/69. Heading B1X. A pressure cooking apparatus comprises an insulated cooking vessel 32 which is electrically heated, a hydraulically operable closure lid (34), Fig. 9 (not shown) to which is affixed racks (33), Fig. 3 (not shown) having supports (35) for grills (23) which carry food to be cooked. The lid (34) is slidable vertically along guide rods (54) Fig. 7 (not shown), by means of a hydraulic cylinder 64 and piston (65) in a hydraulic line (110), (111) which includes a valve (113) to retain the lid in its closure position if the hydraulic pressure fails. An electrically heated premelt tank 58 receives solid cooking fat lowered on a tray (91), Fig. 10 (not shown) by a cord (89) fixed to the tray and a lever 87 actuated by a hydraulic cylinder 85 and a solenoid or motor (96). Cooking liquid is drained from the vessel 32 via an inclined sump (37) and a pipe 159 including a valve 158 into an electrically heated tank 59 with a hollow disc filter 124 from which extends a pipe 125 with a pump 126 to transfer filtered cooking liquid to an electrically heated preheat tank 60. Cooking liquid is passed from the preheat tank 60 to the vessel 32 through a pipe 144 having a valve 145. The volume of liquid in the preheat tank 60 and consequently the amount thereof transferred to the vessel 32 is controlled by a pipe 129 which maintains a fixed level of liquid in tank 60 by draining into the premelt tank 58. Smaller amounts of cooking liquid are added to the vessel 32 from the premelt tank 58 through a pipe 165 with a valve 166. The premelt tank 58 has a pipe 103 with a pump 107 to discharge cooking liquid through a hose to clean the vessel 32. The cooking vessel 32 is vented through a duct 74 which includes a valve 75 and leads to a trap 78 from which extends an exhaust stack 79 and a drain pipe 80. Circuitry containing heating elements, thermostatic switches, motors for actuating the valves and a timer for controlling the cooking period and the interval between lid sealing and opening are also described. The cooking vessel 32 and the preheat tank 60 may have temperature measuring and indicating devices.

Title: Improvements in hydraulic or pneumatic pressure control systems
IPC: F15B1/027
Filed: 1956-10-24
Abstract: 842,017. Fluid-pressure servomotor-control systems; hydraulic accumulators. JOHAN SSON S.A. Oct. 24, 1956, No. 32430/56. Classes 69 (2) and 135. Upon starting a pump 1, pressure liquid flows to consumer apparatus 5 and an accumulator chamber 7 via conduits 2, 3 and a non-return valve 11, whereupon an adjustably spring- loaded accumulator piston 8 is raised until it uncovers the end of a conduit 15, thereby enabling liquid to depress a spring-biased piston 12 and shut-off valve 13, so unloading the pump 1 since conduit 2 is connected to the sump 17 by conduits 18, 16 and the interior of the valve 13. Simultaneously the valve 11 closes and any leakage which occurs is then made up by the accumulator; when the piston 8 returns to the position shown the piston 12 is connected to the sump 17 via conduit 21 and a reduced diameter part of the accumulator piston 8 thus enabling the shut-off valve-spring 19 to return its valve 13 and piston 12 to the closed position shown, whereupon the pump 1 again operates to repeat the cycle. The piston 12 and valve 13 may be an integral member made of a light metal to minimize its inertia. In a modification, a lever transmission is provided between the piston 12 and the shut-off valve 13, and the accumulator piston may incorporate piston-rings, a rubber ring or a leather cuff for sealing purposes; a similar ring may also be associated with the shut-off valve. Another accumulator of greater volume may be directly connected to the pump and the system may be a pneumatic one. The accumulator may be loaded by three nested springs whilst the valves 11 and 13 are located in the accumulator cores with the piston 12 in the accumulator wall. The loading of the accumulator may be effected by a rubber bag filled with gas, the pressure of which may be adjusted by a filling and discharging valve. In another modification, the conduit 15 is controlled by a separate valve actuated directly or indirectly from the accumulator piston, which valve may control separate parallel conduits for inlet to and exhaust from the piston 12. The shut-off valve spring may be replaced by a piston. The conduit 18 may open into the lower part of the shut-off valve casing in which case the shut-off valve must be manually lowered at starting to cover the end of conduit 18; the accumulator piston is modified to take account of this feature. The conduit 18 may open in front of the shut-off valve in which case a separate conduit closing means is provided.
